7. Remove the support blocks and lower the machine to
the shop floor. Test drive the machine to make sure it
does not move when the traction pedal is in neutral.
8. After adjusting the pump plate, check the neutral switch
operation and adjust, if necessary.
Adjusting Neutral Switch
Whenever the pump plate is adjusted, check the neutral
switch (Fig. 54) operation and, if necessary, adjust it as
follows:
1. Park the machine on a level surface and turn the engine
off.
2. Loosen the locknut securing the switch adjusting screw.
Thread it away from the switch until the capscrew head
clears the switch.

3. Adjust switch location until circuit is made when in
neutral and broken with 1 inch travel of traction pedal.
4. Tighten the locknut
Adjusting the Belts
Make sure the belts are properly tensioned to ensure proper
operation of the machine and prevent unnecessary wear. On
new belts, check the tension after 8 hours operation.
Hydraulic Pump Belt
A new hydraulic pump belt should be tensioned so that it
deflects 0.12 inch with a 15–17 pound load applied midway
in the span of the belt. A used belt should be tensioned so
that it deflects 0.12 inch with a 11–13 pound load applied
midway in the span of the belt.
Tighten the nut on the adjustment rod (Fig. 55) until the
desired belt tension is attained.
Note: Tighten the belt to eliminate slippage (squealing
under load) but do not overtighten.

Alternator belt
1. Check tension by depressing belt at mid span of
crankshaft and alternator pulleys with 22 lbs. of force.
A new belt should deflect .3–.5 in. A used belt should
deflect .4–.55 in. If deflection is incorrect, proceed to
next step. If correct, continue operation.
2. To adjust belt tension:
A. Loosen alternator mounting bolts.
B. Using a bar, rotate alternator until proper belt
tension is attained, then tighten mounting bolts.

Adjusting the Traction Pedal
If the traction pedal contacts the footrest when it is pushed
fully forward or maximum forward traction speed is
unattainable, an adjustment to the traction pedal linkage is
required.
1. To expose the traction rod, remove the right panel.
